Port Modes and LEDs
The port modes (Table 2-5) determine the type of information displayed through
the port LEDs. When you change port modes, the meaning of the port LED colors
also changes.
Note The bandwidth utilization mode (UTIL LED) is not displayed on the VSM or
Cluster Manager switch images. Select Monitoring > Bandwidth Graph to
display the total bandwidth in use by the switch. Refer to the switch hardware
installation guide for information about using the UTIL LED.
To select or change a mode, click Mode until the desired mode LED is green.
